Population growth and rapid urbanization makes the crime as a social problem threaten the quality of life. The spatial analysis of crime has geographical dimensions that are disproportionately distributed in geographical scales (national, regional, local). Thus, the aim of this study was to determine the ratio of crime to the population density in the border town of Sar-e Pol-e Zahab in Geographic Information System (GIS) environment. This study is of a descriptive-analytic and applied research type. This study was conducted in Sar-e Pol-e Zahab. The data were collected from offenders who committed robbery in the geographical area of the city. Therefore, all the theft offenses in the city that were committed during 10 years from March 21, 2003 to March 20, 2014 and filed in I.R.I police stations and law enforcement units have been studied.
The findings show that most ration of density of crime to the population could be seen in downtown. The least ratio of crime to the population was also seen in Jihad and Niruye Entezami Settlements. The analysis of the maps of crime relative density (crime per unit area and population) clearly shows the positive correlation of population density. Therefore, as the population density increases in each area, the likelihood of crime commitment increases. Therefore it can be concluded that crimes occur in densely populated areas. The analysis of maps of the crime relative density (crime per unit area and population) clearly shows the direct and positive relationship between population density in different parts of the city and the number of crimes in each neighborhood. Therefore, the more the population density in each area increases the likelihood of crime commitment increases in the area as well.
